Chapter 692 (2/2)
Hard airships are much bigger than hot-air balloons. Take the hard airships owned by the air force of the bear army for example. One air bag of an airship is not much smaller than a hot-air balloon. For the same air bag, there are 13 air bags on one airship!
The hard airship now used by the air force of the storm bear army was built by stone bear imitating the first generation Zeppelin airship.
At this time, there was no way to smelt aluminum. Neither thermal reduction nor electrolytic aluminum could be achieved by the Yanhuang tribe at present. Therefore, the cabin of the airship could not be made of lighter aluminum oxide. Shi Xiong had to let his subordinates build the cabin with thin steel plate and wood.
Above the cabin is an airship with 13 airbags. There is a skeleton made of steel in the boat. The skeleton is composed of a longitudinal abdominal beam, twenty pestles and twelve frames. A large number of longitudinal and transverse stay wires are used to enhance the structural strength. The hull frame is covered with a skin made of cotton cloth coated with tung oil.
There are 13 airbags in the boat, with a total volume of 10000 cubic meters. It is full of hydrogen and has a total buoyancy of 11 tons.
In this era, the source of hydrogen is not difficult, whether it is purified by water gas or by steam and iron heating. Both Shangjing industrial base and Daqingshan industrial base have these two methods of hydrogen purification.
Even the Petroleum Research Institute in buffalo is now studying the use of decomposed oil to produce hydrogen
In a word, the purification of hydrogen is not a problem.
The airship is also equipped with a steering rudder, which can control the lift. At the rear of the airship, a propeller with a diameter of four meters is installed. The power of the propeller is provided by a small steam engine with a weight of 330 kg.
Powered by this steam engine, the airship can fly in the air at a speed of 15 kilometers per hour.
In general, the basic performance of this airship is similar to that of the first generation Zeppelin airship, but slightly inferior to that of the first generation Zeppelin airship in volume and buoyancy.
The weight of the airship is close to seven tons, that is to say, if the airship can fly normally, the cabin of the airship can carry four tons of cargo.
In fact, a few years ago, when the first hard airship carried two tons of stone into the sky and flew 500 kilometers nonstop, the stone bear knew that his ”Kirov” airship bombing team had not run away.
Yes, after the first hard airship successfully completed the test, Shi Xiong named this airship after maozi's Kirov airship in the famous computer game ”Red Alert”. This airship is called ”Kirov class” hard airship.
The power of this thing is really bad. When we did the bombing experiment, everyone was shocked by the power of the projectile thrown down by this thing.
This special ”aviation bomb” used on the airship weighs more than 30 kg, and it is loaded with 8 kg high explosive charge, which is 2 kg more than the later 155 mm high explosive grenade!
This kind of high explosive bomb specially used for airdrop is equipped with a special balance tail, which can ensure that the warhead will always rush down in the process of throwing. The warhead will be equipped with a touch fuse before it is thrown. Once it lands, it will explode, and then all unprotected soft targets within a radius of 45 meters will be cleaned up!
Now, it's finally the turn of this thing to come to the fore in actual combat
